Description

指紋感測裝置Fingerprint sensing device

本新型創作是有關於一種電子裝置，且特別是有關於一種屏下式指紋感測裝置。The creation of this new type relates to an electronic device, and in particular to an under-screen fingerprint sensing device.

近年來，指紋辨識技術被廣泛地應用在各種電子裝置上，以提供身分驗證功能。目前而言，有部份指紋辨識方案是採用將指紋感測裝置配置於電子裝置的背面的方式，但此種指紋辨識方案無法在電子裝置放置於桌面上的情境下使用。此外，伴隨著掌上型電子裝置朝向全面屏的發展趨勢，屏下式指紋（Fingerprint On Display，FOD）辨識方案便被發展出來。In recent years, fingerprint identification technology has been widely used in various electronic devices to provide identity verification functions. At present, some fingerprint recognition schemes adopt the method of arranging the fingerprint sensing device on the back of the electronic device, but this fingerprint recognition scheme cannot be used in a situation where the electronic device is placed on a desktop. In addition, with the development trend of palm-type electronic devices towards full screens, Fingerprint On Display (FOD) identification solutions have been developed.

屏下式指紋辨識方案可分為超音波式與光學式兩種，其中超音波式屏下式指紋辨識方案有成本高及良率低等缺點。光學式屏下式指紋辨識方案是將指紋感測器設置在顯示面板下方，以讓使用者可將手指接觸或按壓在顯示面板上方，以使指紋感測器來取得指紋影像。因此，如何透過簡易且可靠的方式將指紋感測器設置於顯示面板下方為本領域技術人員相當關心的議題。Under-screen fingerprint identification schemes can be divided into ultrasonic and optical types. Among them, under-screen fingerprint identification schemes have the disadvantages of high cost and low yield. The optical under-screen fingerprint identification solution is to set the fingerprint sensor below the display panel, so that the user can touch or press the finger above the display panel, so that the fingerprint sensor can obtain the fingerprint image. Therefore, how to arrange the fingerprint sensor below the display panel in a simple and reliable manner is a subject of considerable concern to those skilled in the art.

本新型創作提供一種指紋感測裝置，其具有較佳組裝可靠度且具有組裝容易的優點。The novel creation provides a fingerprint sensing device which has better assembly reliability and has the advantages of easy assembly.

本新型創作的實施例提出一種指紋感測裝置，其包括指紋感測器、中框，以及支撐板。中框具有開口，而支撐板組裝於該中框上。支撐板包括元件承載部與多個承靠部。指紋感測器配置於元件承載部的上表面。多個承靠部位於元件承載部的相對兩側，且承靠在開口的邊緣。這些承靠部與元件承載部具有一高度差且形成有ㄧ凹槽，且此凹槽位於中框的開口中。The embodiment of the present invention proposes a fingerprint sensing device, which includes a fingerprint sensor, a middle frame, and a support plate. The middle frame has an opening, and the support plate is assembled on the middle frame. The support plate includes an element bearing portion and a plurality of bearing portions. The fingerprint sensor is disposed on the upper surface of the element carrying part. The plurality of bearing portions are located on opposite sides of the element bearing portion, and bear against the edge of the opening. The bearing portion and the component bearing portion have a height difference and a groove is formed, and the groove is located in the opening of the middle frame.

基於上述，本新型創作的實施例至少具有以下其中一個優點，指紋感測器藉由支撐板而組裝於中框上，而使指紋感測器可穩固地設置於顯示面板下方，以使指紋感測裝置可提供屏下式指紋辨識功能。此外，本新型創作的實施例無須將指紋感測器直接貼附於顯示面板上，而可避免顯示面板損傷。藉此，本新型創作的指紋感測裝置具有較佳組裝可靠度且具有組裝容易的優點。Based on the above, the embodiment of the present invention has at least one of the following advantages. The fingerprint sensor is assembled on the middle frame by the support plate, so that the fingerprint sensor can be stably placed under the display panel to make the fingerprint sense The test device can provide under-screen fingerprint identification. In addition, the embodiments of the present invention do not require the fingerprint sensor to be directly attached to the display panel, which can avoid damage to the display panel. Thereby, the fingerprint sensing device created by the present invention has better assembly reliability and has the advantages of easy assembly.

為讓本新型創作之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the creation of the new model more obvious and understandable, the embodiments are specifically described below and described in detail in conjunction with the attached drawings.

有關本新型創造之前述及其他技術內容、特點與功效，在以下配合參考圖式之多個實施例的詳細說明中，將可清楚的呈現。以下實施例中所提到的方向用語，例如「上」、「下」、「前」、「後」、「左」、「右」等，僅是參考附加圖式的方向。因此，使用的方向用語是用來說明，而非用來限制本新型創造。The foregoing and other technical contents, features, and effects of the creation of the new model will be clearly presented in the following detailed descriptions with reference to the multiple embodiments of the drawings. Directional terms mentioned in the following embodiments, such as "upper", "lower", "front", "rear", "left", "right", etc., are for reference only to the directions of the attached drawings. Therefore, the terminology used is for illustration, not for limiting this new type of creation.

圖1是一種指紋感測裝置的示意圖。請參照圖1，指紋感測裝置100提供有屏下指紋辨識功能，使用者可將手指F1按壓顯示面板150上方的玻璃蓋板，以使顯示面板150下方的指紋感測器可取得指紋影像。指紋感測器的感測範圍例如圖1的指紋感測區域A1，但本新型創作對此不限制。指紋感測裝置100例如是智慧型手機（smart phone）、平板（panel）、遊戲機或其他具有光學式屏下指紋辨識功能的電子裝置，本新型創作對此不限制。FIG. 1 is a schematic diagram of a fingerprint sensing device. Referring to FIG. 1, the fingerprint sensing device 100 provides an off-screen fingerprint recognition function. The user can press the finger F1 on the glass cover above the display panel 150 so that the fingerprint sensor below the display panel 150 can obtain fingerprint images. The sensing range of the fingerprint sensor is, for example, the fingerprint sensing area A1 in FIG. 1, but the creation of the new model does not limit this. The fingerprint sensing device 100 is, for example, a smart phone, a panel, a game console, or other electronic devices with an optical under-screen fingerprint recognition function, which is not limited by the creation of the new model.

圖2是依照本新型創作一實施例的指紋感測裝置的剖面示意圖。圖3是依照本新型創作一實施例的支撐板的立體示意圖。圖4是依照本新型創作一實施例的中框的俯視示意圖。請先參照圖2與圖3，指紋感測裝置100可包括指紋感測器110、中框120、支撐板130、軟性電路板140、顯示面板150、緩衝件160a與160b。2 is a schematic cross-sectional view of a fingerprint sensing device according to an embodiment of the present invention. FIG. 3 is a perspective schematic view of a supporting plate according to an embodiment of the novel creation. 4 is a schematic top view of a middle frame according to an embodiment of the present invention. Please refer to FIGS. 2 and 3 first. The fingerprint sensing device 100 may include a fingerprint sensor 110, a middle frame 120, a support plate 130, a flexible circuit board 140, a display panel 150, buffers 160a and 160b.

於一實施例中，指紋感測器110可包括由多個感測畫素組成的感測畫素陣列，這些感測畫素各自包括用以進行光電轉換的至少一個光電二極體（photodiode）。指紋感測器110也可包括與上述感測畫素陣列連接的相關電路。於一實施例中，指紋感測器110還可包括配置於感測畫素陣列上方的其他光學元件，像是透鏡、準直器、濾光層等等，本新型創作對此不限制。指紋感測器110可實作為一晶片，或上方配置有光學元件的晶片，本新型創作對此不限制。此外，本實施例是以一個指紋感測器110為例進行說明，但本新型創作對於指紋感測器的數量並不限制。In an embodiment, the fingerprint sensor 110 may include a sensing pixel array composed of a plurality of sensing pixels, each of which includes at least one photodiode for photoelectric conversion . The fingerprint sensor 110 may also include related circuits connected to the sensing pixel array. In an embodiment, the fingerprint sensor 110 may further include other optical elements disposed above the sensing pixel array, such as a lens, a collimator, a filter layer, and the like, which is not limited by the creation of the present invention. The fingerprint sensor 110 can be implemented as a chip, or a chip with optical elements arranged on it, and the creation of the present invention does not limit this. In addition, this embodiment takes one fingerprint sensor 110 as an example for description, but the creation of the present invention does not limit the number of fingerprint sensors.

顯示面板150可採用具有自發光顯示元件的顯示面板，例如為有機發光二極體（Organic Light-Emitting Diode，OLED）顯示面板，但本新型創作並不限於此。在進行指紋感測時，使用者將手指放置於顯示面板150上方，而顯示面板150會發出照明光束照射至手指，經手指反射而產生的反射光束會傳遞至指紋感測器110以進行指紋感測。The display panel 150 may adopt a display panel with a self-luminous display element, such as an organic light-emitting diode (OLED) display panel, but the creation of the new type is not limited to this. During fingerprint sensing, the user places the finger above the display panel 150, and the display panel 150 emits an illumination beam to the finger, and the reflected beam generated by the finger reflection is transmitted to the fingerprint sensor 110 for fingerprint sensing Measurement.

中框120（middle frame）為指紋感測裝置100中用以承載內部各種裝置元件的框架，上述裝置元件可以為主機板、攝像裝置、麥克風或各種感測器等等。於一實施例中，中框120為金屬材質或其他硬性材質，亦可用以支撐顯示面板150。為了讓指紋感測器110可接收到手指反射的光束，中框120具有一開口125，其用以容置指紋感測器110。以圖1的範例為例，開口125即位於指紋感測區域A1的正下方，且開口125的大小至少大於指紋感測器110。The middle frame 120 (middle frame) is a frame used to carry various internal device elements in the fingerprint sensing device 100. The above device elements may be a motherboard, a camera device, a microphone, various sensors, or the like. In one embodiment, the middle frame 120 is made of metal or other rigid materials, and can also be used to support the display panel 150. In order to allow the fingerprint sensor 110 to receive the light beam reflected by the finger, the middle frame 120 has an opening 125 for accommodating the fingerprint sensor 110. Taking the example of FIG. 1 as an example, the opening 125 is located directly under the fingerprint sensing area A1, and the size of the opening 125 is at least larger than the fingerprint sensor 110.

在一實施例中，支撐板130用以承載指紋感測器110，並組裝於中框120上。支撐板130可為金屬材質或其他硬性材質，本新型創作對此不限制。請參照圖2與圖3，支撐板130包括元件承載部131與多個承靠部133a、133b。元件承載部131用以承載指紋感測器110，其面積大於指紋感測器110。承靠部133a、133b位於元件承載部131的相對兩側。於一實施例中，元件承載部131與多個承靠部133a、133b為一體成型的結構。承靠部133a、133b與元件承載部131具有一高度差而形成有凹槽，且用以容置指紋感測器110的凹槽位於中框120的開口125中。換言之，支撐板130的承靠部133a、133b是將支撐板130兩側向上彎折而形成。承靠部133a、133b承靠在開口125的邊緣處，使得配置有指紋感測器110的凹槽可置於中框120的開口125中。承靠部133a、133b可固定於中框120的上表面。於一實施例中，開口125的邊緣可經削薄處理而具有階梯狀的卡槽結構（例如圖2與圖4所示的卡槽結構121），此卡槽結構的較低表面適於承放承靠部133a、133b。換言之，承靠部133a、133b可固定於中框120的卡槽結構的較低表面上，因而防止指紋感測器110過於靠近顯示面板150。或者，於一實施例中，開口125的邊緣可未經其他加工處理，而承靠部133a、133b可直接固定於中框120未經加工處理之上表面。指紋感測器110與顯示面板150之間具有一間隙。由此可知，指紋感測器110可藉由支撐板130而與中框120固定連接，而無須直接將指紋感測器110固定在顯示面板150上。In one embodiment, the support plate 130 is used to carry the fingerprint sensor 110 and is assembled on the middle frame 120. The supporting plate 130 may be made of metal or other hard materials, and the creation of the new type does not limit this. Please refer to FIGS. 2 and 3. The support plate 130 includes an element bearing portion 131 and a plurality of bearing portions 133 a and 133 b. The element carrying portion 131 is used to carry the fingerprint sensor 110, and its area is larger than the fingerprint sensor 110. The bearing portions 133 a and 133 b are located on opposite sides of the element carrying portion 131. In an embodiment, the component carrying portion 131 and the plurality of bearing portions 133a and 133b are integrally formed. The bearing portions 133a, 133b and the element carrying portion 131 have a height difference and are formed with grooves, and the groove for accommodating the fingerprint sensor 110 is located in the opening 125 of the middle frame 120. In other words, the bearing portions 133a and 133b of the support plate 130 are formed by bending both sides of the support plate 130 upward. The bearing portions 133a, 133b bear against the edge of the opening 125, so that the groove configured with the fingerprint sensor 110 can be placed in the opening 125 of the middle frame 120. The bearing portions 133a and 133b may be fixed to the upper surface of the middle frame 120. In an embodiment, the edge of the opening 125 may be thinned to have a stepped slot structure (such as the slot structure 121 shown in FIGS. 2 and 4 ). The lower surface of the slot structure is suitable for supporting The bearing portions 133a and 133b. In other words, the bearing portions 133a and 133b can be fixed on the lower surface of the slot structure of the middle frame 120, thereby preventing the fingerprint sensor 110 from being too close to the display panel 150. Alternatively, in an embodiment, the edge of the opening 125 may be unprocessed, and the bearing portions 133a and 133b may be directly fixed to the unprocessed upper surface of the middle frame 120. There is a gap between the fingerprint sensor 110 and the display panel 150. It can be seen that the fingerprint sensor 110 can be fixedly connected to the middle frame 120 through the supporting plate 130 without directly fixing the fingerprint sensor 110 on the display panel 150.

在本實施例中，支撐板130更包括多個連接部132a、132b，連接部132a、132b連接於元件承載部131與承靠部133a、133b之間，且連接部132a、132b為傾斜平面。連接部132a、132b的傾斜程度可視實際應用而決定，本新型創作對此不限制。In this embodiment, the support plate 130 further includes a plurality of connecting portions 132a and 132b. The connecting portions 132a and 132b are connected between the element carrying portion 131 and the bearing portions 133a and 133b, and the connecting portions 132a and 132b are inclined planes. The degree of inclination of the connecting parts 132a and 132b can be determined according to actual applications, and the creation of the present invention does not limit this.

在本實施例中，元件承載部131的寬度d1相同於承靠部133a、133b的寬度d2。藉此，不僅承靠部133a、133b較不易變形，且支撐板130可透過承靠部133a、133b而可靠地組裝置中框120上。此外，請先參照圖2與圖4，在本實施例中，開口125的邊緣具有呈現階梯狀的卡槽結構121，而承靠部133a、133b可抵接於卡槽結構121的較低表面上。亦即，卡槽結構121用以卡合承靠部133a、133b，不僅使支撐板130便於組裝，也可使支撐板130可穩固地組裝於中框120上。在支撐板130的高度（自承靠部133a、133b的上表面至的元件承載部131的下表面）小於中框120的厚度的實施例中，更可使指紋感測器100的存在不會造成指紋感測裝置100的裝置厚度增加。In this embodiment, the width d1 of the element carrying portion 131 is the same as the width d2 of the bearing portions 133a and 133b. In this way, not only the bearing portions 133a and 133b are easily deformed, but also the supporting plate 130 can be reliably assembled on the device middle frame 120 through the bearing portions 133a and 133b. In addition, please refer to FIGS. 2 and 4 firstly. In this embodiment, the edge of the opening 125 has a stepped slot structure 121, and the bearing portions 133 a and 133 b can abut against the lower surface of the slot structure 121 on. That is, the clamping groove structure 121 is used to engage the bearing portions 133a and 133b, which not only makes the support plate 130 easy to assemble, but also enables the support plate 130 to be stably assembled on the middle frame 120. In the embodiment where the height of the support plate 130 (from the upper surface of the bearing portions 133a, 133b to the lower surface of the element carrying portion 131) is less than the thickness of the middle frame 120, the presence of the fingerprint sensor 100 is further prevented As a result, the thickness of the fingerprint sensing device 100 increases.

在本實施中，軟性電路板（FLEXIBLE PRINTED CIRCUIT，FPC）140疊合於指紋感測器110與支撐板130的元件承載部131之間。軟性電路板140可透過黏膠材料而固定於支撐板130之上，而指紋感測器110可透過黏膠材料而固定於軟性電路板140之上。軟性電路板140的材質為可撓性材質。指紋感測器110配置於軟性電路板140上，且指紋感測器110可與軟性電路板140的線路層電性連接，使指紋感測器110可透過軟性電路板與外部電路電性連接。藉此，指紋感測器110可將指紋感測資料提供給指紋感測裝置100的其他處理單元。In the present embodiment, the flexible printed circuit (FLEXIBLE PRINTED CIRCUIT, FPC) 140 is superposed between the fingerprint sensor 110 and the element carrying portion 131 of the support plate 130. The flexible circuit board 140 can be fixed on the support board 130 through an adhesive material, and the fingerprint sensor 110 can be fixed on the flexible circuit board 140 through an adhesive material. The material of the flexible circuit board 140 is a flexible material. The fingerprint sensor 110 is disposed on the flexible circuit board 140, and the fingerprint sensor 110 can be electrically connected to the circuit layer of the flexible circuit board 140, so that the fingerprint sensor 110 can be electrically connected to an external circuit through the flexible circuit board. In this way, the fingerprint sensor 110 can provide fingerprint sensing data to other processing units of the fingerprint sensing device 100.

在本實施中，顯示面板150具有保護層151，用以防止顯示面板150受到損傷。保護層151可以是由楊氏模數（Young's modulus）較低之材料所構成，因此會產生緩衝的作用。為了讓手指反射的光束可以盡量不受到干擾地傳遞至指紋感測器110，保護層151也具有開口。In this embodiment, the display panel 150 has a protective layer 151 to prevent the display panel 150 from being damaged. The protective layer 151 may be composed of a material with a low Young's modulus, so it will have a buffering effect. In order for the light beam reflected by the finger to be transmitted to the fingerprint sensor 110 without interference as much as possible, the protective layer 151 also has an opening.

在本實施中，緩衝件160a、160b配置於軟性電路板140上，且位於指紋感測器110的兩側。緩衝件160a、160b連接於保護層151與軟性電路板140之間。於一實施例中，各緩衝件160a、160b可為泡綿，可用以吸收手指按壓顯示面板150進行指紋辨識的向下力道，從而避免顯示面板150或指紋感測器110受到損傷。In this embodiment, the buffers 160a and 160b are disposed on the flexible circuit board 140 and located on both sides of the fingerprint sensor 110. The buffers 160a and 160b are connected between the protective layer 151 and the flexible circuit board 140. In an embodiment, each buffer member 160a, 160b may be a foam, which can be used to absorb the downward force of the finger pressing the display panel 150 for fingerprint recognition, so as to prevent the display panel 150 or the fingerprint sensor 110 from being damaged.

需說明的是，支撐板130的承靠部133a、133b可透過黏膠層或鎖附件而固定於中框120的上表面。圖5A是依照本新型創作一實施例的支撐板透過黏膠層固定於中框的示意圖。請參照圖5A，支撐板130的承載部133a、133b可透過黏膠層51而黏在中框120上。或者，圖5B是依照本新型創作一實施例的支撐板透過鎖附件固定於中框的示意圖。請參照圖5B，支撐板130的承載部133a、133b可透過鎖附件52（例如螺絲）而固定於支撐板120上。對應的，中框120與承載部133a、133b分別設置有適於讓鎖附件52穿過的定位孔。It should be noted that the bearing portions 133a and 133b of the support plate 130 can be fixed to the upper surface of the middle frame 120 through an adhesive layer or a lock attachment. FIG. 5A is a schematic diagram of a supporting plate fixed to a middle frame through an adhesive layer according to an embodiment of the present invention. Referring to FIG. 5A, the bearing portions 133a and 133b of the support plate 130 can be adhered to the middle frame 120 through the adhesive layer 51. Alternatively, FIG. 5B is a schematic diagram of the supporting plate fixed to the middle frame through the lock attachment according to an embodiment of the present invention. Referring to FIG. 5B, the bearing portions 133a and 133b of the support plate 130 can be fixed to the support plate 120 through the lock attachment 52 (for example, screws). Correspondingly, the middle frame 120 and the bearing portions 133a and 133b are respectively provided with positioning holes suitable for the lock attachment 52 to pass through.

基於上述，本新型創作的實施例至少具有以下其中一個優點，指紋感測器藉由支撐板而組裝於中框上，而使指紋感測器可穩固地設置於顯示面板下方，以使指紋感測裝置可提供屏下式指紋辨識功能。此外，本新型創作的實施例無須將指紋感測器直接貼附於顯示面板上，而可避免顯示面板損傷。再者，由於支撐板與中框皆屬於硬性材質，二者之間的固定連接有許多實現方式，從而達成依據實際需求而便於組裝的目的。Based on the above, the embodiment of the present invention has at least one of the following advantages. The fingerprint sensor is assembled on the middle frame by the support plate, so that the fingerprint sensor can be stably placed under the display panel to make the fingerprint sense The test device can provide under-screen fingerprint identification. In addition, the embodiments of the present invention do not require the fingerprint sensor to be directly attached to the display panel, which can avoid damage to the display panel. Furthermore, since both the support plate and the middle frame are hard materials, there are many ways to implement the fixed connection between the two, so as to achieve the purpose of easy assembly according to actual needs.

綜上所述，本新型創作將指紋感測器配置於支撐板的凹槽中，並將支撐板固定於中框上。藉此，可使指紋感測器可穩固且可靠地設置於顯示面板下方，以使指紋感測裝置可提供屏下式指紋辨識功能。本新型創作的實施例無須將指紋感測器直接貼附於顯示面板上，而可避免顯示面板損傷。並且，本新型創作可在不影響顯示面板的情況下對指紋感測器進行為修作業。再者，由於支撐板與中框皆屬於硬性材質，二者之間的固定連接有許多實現方式，從而達成依據實際需求而便於組裝的目的。In summary, in the creation of the new model, the fingerprint sensor is arranged in the groove of the support plate, and the support plate is fixed on the middle frame. In this way, the fingerprint sensor can be stably and reliably arranged under the display panel, so that the fingerprint sensing device can provide the off-screen fingerprint recognition function. The embodiment of the present invention does not need to directly attach the fingerprint sensor to the display panel, and can avoid damage to the display panel. Moreover, the creation of the new model can repair the fingerprint sensor without affecting the display panel. Furthermore, since both the support plate and the middle frame are hard materials, there are many ways to implement the fixed connection between the two, so as to achieve the purpose of easy assembly according to actual needs.
